Things To Do on Wednesday, August 21.

Seek Out The Book of Mormon.

Unless you grew up the child of a tyrant, chances are that you — along with most everyone else in the world — didn't always fellow the directions on the Lego sets your parents would buy you from time to time. More likely, you just did whatever the hell you wanted, using any and every brick you could find, regardless of color and sometimes even shape, to create a sculpture or world of your choosing.

And y'know what? They didn't have an instruction pamphlet lying around to help them out.

Keep that in mind this evening as you plan your night around town: Guidelines are for chumps. Try something new.

Just, um, don't try going to the Legoland Discovery Center at the Grapevine Mills Mall tonight if you don't have a young 'un in tow; the next adult night here isn't until September 23.

The Book of Mormon at Winspear Opera HouseThe Book Of Mormon, a musical trip into the heart of America's unique homegrown religion from the creators of South Park, has won countless awards, sold out everywhere its gone and is absolutely hysterical. Unfortunately, if you've waited until now to buy your tickets, you've probably missed your opportunity to purchase any at face value. Hey, you can always pay the steep markup added by ticket brokers like Stubhub! Listen: There are certainly worse things in the world to spend your money on. The collection plate, perhaps? — Stephen Young

Human Behavior, Joey Kendall, Fishboy and Timothy Jarrod Smith at J&J's PizzaTuscon-based “psych-punk dramedy band” Human Behavior kicks off the first of a two-night DFW swing tonight in Denton. Or as we prefer to think of this show: It's an opportunity to travel back to 2009 when sets by Joey Kendall, Fishboy and Hot Coffins frontman Timothy Jarrod Smith in the dingy confines of the J&J's basement occurred with much more frequency. Ah, those were the days. — Cory Graves

Dovetail at SundownExpect locals Dovetail to showcase their driving rhythms and intricate harmonies at this edition of their all-August-long Wednesday night residency at Sundown. The band just re-released their 2012 album Mount Karma after signing with New Jersey's Ok!Good records, so expect them to go heavy on material from that record, too. — SY

Elvis Impersonator Contest at El RanchitoTonight, Oak Cliff eatery El Ranchito will forego their typical mariachi barrage for the second (and final) round of their Elvis impersonator contest. Don't worry, they'll still be serving up the best — or at the very least the most underrated — margaritas in town. Reservations are also very much recommended. — CG

Art With A View at The Belmont HotelTonight provides yet another worthy occasion to venture to the great beyond that lays past the Margaret Hunt Hill Bridge: The art on display at the historic Belmont Hotel tonight comes courtesy of mixed media artist and original Brutal Juice bassist Richard Ross. — CG
